To alli/whom t may concern: i

Be it known that I, Jer-IN F. REMY, a

citizen of the United States, residing at advance ofV another, the forward gang being mounted in the main frame, and the object of the invention is to provide simple, inexpensive and efficient means whereby suiiicient pressure will be exerted upon the rear gang to hold the same to its work. Y

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the claims.Y

In the drawings:

Figure 1 is a perspective view of a pulverizer having my improvement applied thereto;

Fig. 2 is an end elevation of the same;

Fig. 3 is a rear elevation of one end of the Vpulverizer.

The main frame 1 may be ofthe usual or any preferred construction and is illustrated as provided with a draft tongue or pole which is supported upon a steering truck 2 at its front end which truck may be dispensed with if'the pulverizer be drawn by a tractor. The frame is also equipped with a spnjing standard 3 supporting a drivers seat 1. To the ends of the frame, I secure hangers or brackets 6 having journal boxes 7 at their lower ends in which is mounted the axle ofthe forward gang of pulverizer disks 9. A dust cap 8 is. arranged over the end of the axle and is bolted to the ournal box 7 as shown at 80. The disks may be of any well-known or preferred form and are illustrated as having their circumferential surfaces converging from their ends toward their centers, so as to provide central annular ridges 10 which will take into the ground and thoroughly cutupand pulverize the same. To the hangers or brackets 6 I pivotally secure the front ends of lever arms 11 having their rear ends formed into sleeves or collars 12 which encircle the axle of the rear gang of disks 14. A dust cap 13 fits over the end of the axle and is secured to the collar 12, as shown at 130. AThe collar 12 is provided at its inner end with a depending lug 15 and a similar lug 16 is provided on the under side of the spacing and bearing sleeve 1,7, ldisposed about the axle between the end disks 14 and the inner end of the sleeve 12. A bolt 1S is inserted through the lugs 15 and 1G so as to hold the 'members'12 and. 17 together. Upon the upper sides'of the sleeves 12 and 17 are lugs or ears 19 through which is inserted a pivot bolt 20,

and said bolt isengaged between the said lugs or ears by an eye 21 on the lower rear end of a rod 22 which passes upwardly and4 forwardly and playsl freely in a combined stop and guide shown as an eye 23 secured in the upper portion of the adjacent bracket or hanger 6, but may be provided on the lower or rear portion thereof. A spring 24: is coiled around the rod 22 between the eye 23 and a collar 25 fitted loosely upon the rod and held in any adjusted position by a set screw 26, as will be readily understood. Obviously, by adjusting the collar, the tension of the spring may be regulated as desired.

It is thought that the uses and advantages of my invention will be readily understood. In order to effectually perform its intended work, the pulverizer must exert a certain amount of pressureupon the ground, in order that the disks `will properly enter the soil and pulverize the same.' The weight of the main frame is borne principally by the front gang of disks, so that suiiicient pressure is applied to the said front gang of disks to accomplish the desired results. Ordinarily, however, the rear gang of disks exerts no pressure except that due to its own weight and if the soil should be very hard or if obstructions be encountered, the rear gang will not properly penetrate the soil and it is necessary to drive over the ield several times before the soil is brought into proper condition. By providing the rod 22 and the spring coacting therewith, I accomplish the desired result and hold the rear gang to its work so that it will properly penetrate the soil and at the same time will yield to large rocks or similar obstructions sufficiently to avoid damage to any of the parts of the machine.

Having thus described the invention, what is claimed as new is:

1. The combination with a pulverizer comprising a frame, and a gang of disks mounted in said frame, of supporting arms pivoted to the lower portions of the end members of the frame and extending rearwardly therefrom, a gang of ground-en aging members supported by and exten ing between the rear ends of said supporting arms, a relatively stationary guide on the end of the frame above the adjacent pivoted supporting arm and in advance of the gang of ground-engaging members, a rod pivoted at its lower rear end to the adjacent supporting arm and extending upwardly and forwardly therefrom and having its upper forward end playing freely in the guide, an adjustable stop on said rod, and a spring coiled around the said rod between said stop and the guide on the frame and exerting downward pressure on the supporting arm.

2. In a pulverizer, the combination of a frame, a gan of disks mounted in said frame, a gui e on the frame, supporting arms pivoted at their front ends to the frame and extending downwardly and rear wardly therefrom, a second gano of disks mounted between the rear ends of said supporting arms, a'rod pivoted at its lower rear Y Vand playing freely in the guide on the frame,

a collar 'adjustably mounted on said rod, and a spring coiled around the rod between said collar and said guide.

3. In a pulverizer, the combination of a frame, a gang of disks mounted in said frame, supporting arms pivoted at their front ends to the'frame and having collars at theirjlower rear ends,-a -gang of disks mounted between the rear ends o-f said arms, sleeves interposed between the collars and the end disks of the gang of disks, means for connecting the sleeves with the collars, guides' on the ends of the frame, rods pivoted at their lowei` ends on said connecting means and playing vat their upper ends freely in the guides on the' frame, and a spring coiled around each rod between the respective guide and supporting arm.

In testimony whereof I ailix my signature;
